Given numbers are 894,378,715,642,748
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 894,378,715,642,748 is 146503096740.
Find LCM of 894,378,715,642,748 with Prime Factorization
| 2 | 894, 378, 715, 642, 748 |
| 3 | 447, 189, 715, 321, 374 |
| 11 | 149, 63, 715, 107, 374 |
| 149, 63, 65, 107, 34 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 149 x 63 x 65 x 107 x 34 = 146503096740
Therefore, the lowest common multiple of 894,378,715,642,748 is 146503096740.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
894 x 378 x 715 x 642 x 748 = 116030452618080
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
894 : 1, 2, 3, 6, 149, 298, 447, 894
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
715 : 1, 5, 11, 13, 55, 65, 143, 715
642 : 1, 2, 3, 6, 107, 214, 321, 642
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 894,378,715,642,748, is 1.
Now, the common factors can be found like this.
894:2x 3x 149
378:2x 3x 3x 3x 7
715:5x 11x 13
642:2x 3x 107
748:2x 2x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 3x 11 = 792
Therefore, the value for common factors is 792.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 116030452618080/(1x792)
LCM = 116030452618080/792
LCM = 146503096740
Thus, we can understand that the LCM of 894,378,715,642,748 is 146503096740.
